Looking at the pitch-black sea, Yang Congyi began to be a little anxious and worried.

Suddenly, a light flashed on the surface of the sea next to it, and a light lit up.

Just as Yang Congyi was overjoyed and wanted to confirm it again, the point of light flashed and suddenly disappeared again.

A moment later, another point of light lit up on the surface of the sea, but it was the same as before, and after a few breaths, it disappeared.

After that, there were other points of light, and as soon as they lit up, they immediately went out.

The light on the surface of the sea went on and off, and after I don't know how many times, finally there was no light again.

This situation was expected by Yang Congyi, and how to solve it was the top priority.

"My lord, why don't you hang the lantern on the mast?" When a sergeant saw the lights on and off, needless to say, he knew that it was all the fish in the water that were doing the trick.

If the lanterns are hung low, they will definitely be doused by the fish spray and hung on the mast, can they still get on the boat and climb the mast? That's the way to go.

"Okay, get a lantern and hang the mainmast." Yang Congyi was overjoyed and immediately agreed.

In a short time, a lantern was brought up, and a rope was tied to the lantern.

This was an opportunity to perform, and immediately a sergeant who was good at climbing trees volunteered, grabbed the lantern, and climbed up the mainmast.

The main mast was three or four feet high, and the sergeant climbed halfway, and for the sake of safety, Yang Congyi did not let him climb again, and ordered him to hang the lantern on the spot.

When the lantern hung on the mast, the deck was much brighter, and the tension on the ship was much lighter.

The lanterns on the warship are lit up, but how to inform the ships to hang the lanterns on the masts is a problem, they are so far away that they can't hear the shouts, and they can't see the flags, so they can only understand it by themselves?

It didn't take long to listen to "knock ......"

The frequency of the fish hitting the hull of the ship suddenly increased, and the sound became louder and louder, clearer and more dull.

This kind of abnormality, Yang Congyi couldn't have discovered it, and before he could give the order, a sergeant walked to the side of the ship.

"My lord, is this fish crazy?" A sergeant helped the side of the ship, and felt as if the hull of the ship was shaking.

The sergeants, who clearly felt the sound of the impact getting louder and louder, tightened their nerves that had just relaxed again.

The fish were attracted to the light, and I was afraid that the fleet had entered the sea after dark, and happened to meet them, and they happened to be attracted by the very conspicuous light in the night, so they chased all the way, spitting water and playing until the lantern was extinguished.

Now that the lanterns are hung on the masts, they jump up and spit water, and it is inevitable that they will hit the ship. If it is a small fish, you can hit them casually, but just a cursory look, heavy rain is very common to be five or six feet tall, and there may be a bigger king of fish, no matter how big and strong this warship is, it is also made of wood, and the number of times the big fish hits is too much, there will be cracks in it, and if the bigger and longer king of fish also comes to strike, the warship does not dare to say that it will not be 100% broken.

But if the lantern is not lit, the dozens of ships behind will lose navigation, although it is still in the territory of the Great Song Dynasty, so that the fleet behind will not be lost, lost in the vast and boundless sea, but it is inevitable to delay the fleet's trip. The point is that the navigation disappears, and the ships behind lose their following target, which causes them to panic greatly, and once panic begins, the potential danger is unpredictable.

Yang Congyi's thoughts turned sharply, and he suddenly said loudly: "Extinguish the lantern!" ”

Before the words were finished, a sergeant quickly climbed up the mast, took off the lantern, and slid onto the deck in three or two strokes. The other sergeants immediately took the lantern and extinguished it.

The deck was plunged into darkness again.

"What kind of ghost fish is this, it's really evil."

"But isn't it, knock on the ship's board, and you're not afraid of pain?"

"I don't know if this black light is blinding, can they still hit it?"

"The lanterns weren't hung up just now, and they didn't crash into the boat."

"I just don't know if this ship can get up and they hit like this."

.........

For a while, there was a lot of discussion on the deck, and the sound of the impact of sea fish directly drowned it out.

"Silence."

Yang Congyi gave an order, and all the sergeants immediately closed their mouths.

"It's okay to go back to the cabin and rest first."

The sergeants slowly turned around and returned to the cabin.

Not long after, there were only a dozen sergeants left on the deck.

As soon as the ship's lanterns went out, the sound of the crash gradually thinned out. After a while, the sound became lower, and slowly returned to the point where the lantern had been hung.

The fish don't collide with the boat, but the problem of navigation cannot be solved.

Yang Congyi didn't know how anxious the few seagoing ships that couldn't light up the navigation lanterns were, and he didn't know that the seagoing ships that had lost their navigation were anxious at the moment. But he knew they must be having a hard time right now.

Because he is the same, looking at the boundless darkness at this time, he is also at a loss.

He was responsible for guarding dozens of sea ships in the middle, and now the navigation disappeared and could not keep up with the front ship, and the rear ship also lost its following target. Although every ship is equipped with a needle disc, as long as the direction does not deviate by hundreds of miles, the helmsman will not be able to detect it at all.

Now not only are the lights of these ships turned off and they can't find a specific direction, but the seventy or eighty ships behind have also lost their direction because the lights of the front ship have been turned off.

In more serious cases, if the night watchman of the ship behind is napping and does not see the lights of the ship in front of them go out because of an accident, when they find that they have lost navigation, will they suspect that the ship in front has increased its speed, or that their own speed is too slow. If that's the case, speeding up is their inevitable choice.

Any of the ships behind begins to pick up speed, it is not just a matter of this one ship, but of the whole, and all the ships behind it must increase their speed, only then they will not get too far from the ship in front and lose their navigation target.

In this way, danger is coming.

In the dark sea, once the front ship collides with the ship that has lost the ability to navigate, the rear ship will not be able to detect it at all, and it will follow the navigation ship in front of it, full of cargo, the speed of the ship is too fast, and the situation cannot be seen clearly in the dark night, and the rear ship will inevitably collide with the front ship with the lights on. The three ships in front collided together, and the ships following behind would still be unknown, repeating the same fate and continuing to collide upwards. In this way, a great tragedy will be staged.

Thinking of this series of situations and consequences, Yang Congyi broke out in a cold sweat.

This must not happen, or the whole fleet will be finished.

The lights of the five ships are extinguished, and it is almost a quarter of an hour, and not a single light has been lit yet, and I am afraid that no solution has been thought of.

But if you wait, even if the horn sounds, in addition to increasing the panic of the ships, it will not solve the problem of losing navigation in front of you.

What to do? What can I do?

The battlefield could have been lit up, but the lights were so weak that it could not be navigated for all the ships, and as soon as the lights were turned on, they were attacked by the big fish that followed in the sea, and they did not know how much force the warship could prevent from colliding, and there were four hundred people on board, so he could not take this risk.

But now the situation will get worse and worse with the passage of time, and if there is no solution, what will happen later, he can't imagine.

Yang Congyi came to the side of the ship, quietly looked down, and found that he was thinking too much, the sea fish did not leave because the lantern on the boat went out, they were still jumping forward with the boat, and from time to time you could see fish hitting the hull, although there were fewer fish hitting the boat, but the people who followed the warship were still black, and they couldn't see how many there were.

It seems that the fish will not retreat anytime soon, and it is not known when they will stop.

A quarter of an hour is coming, dozens of ships have lost navigation, what can be done?

"The lantern can't be lit, what can you do?" Yang Congyi was helpless, so he had to ask the sergeant who was still on the deck.

The sergeants were silent, and the overseers couldn't think of a way, what could they think? Wouldn't it be in vain to ask them?

Yang Congyi couldn't help but sigh secretly, and asked them what was the use, he was not Zhuge Liang, and they were not generals.

Just as he was looking at the dark sea and meditating, someone suddenly spoke up and gave a suggestion.

I only listened to the man: "My lord, you see if this will work, we will pick up the lantern on the spear, light it and hold it up, and before the fish in the sea can react, we will put out the lamp." If you do this repeatedly, the lights will not go out, and the fish in the sea will not hit the boat too much. ”

As soon as he heard this, Yang Congyi was immediately overjoyed.

This is indeed a way, although the operation is more troublesome, but it is also an expedient measure, intermittent lighting, can fully meet the needs of navigation, whether it is a quarter of an hour a light, or two quarters of an hour a light, will not have much impact on the navigation effect, after all, the rear ship adjusts the direction, is not constantly adjusting the tail rudder, generally half an hour or an hour to adjust once, intermittent lights can be navigated.

"Shi Xing, take credit to you!" Yang Congyi immediately patted Shi Xing's shoulder as a reward.

"Thank you, sir." Shi Xing immediately thanked him.

But this method of intermittently lighting the lantern was unknown to other sea vessels, that is, he hung the lantern on the mast, and the light was always on, and he estimated that the people on the sea boat could not see where it was hanging, and could not figure it out.

If you want to shout to them and they can hear them clearly, you must be within fifty feet, but in the dark sea, if the other party does not turn on the lights, he will not be able to see at all, so if you get close, there is a great danger of hitting the ship.

"Let's navigate all the boats. The lights are gone, so bring the fireworks! After Yang Congyi clarified his thoughts, he quickly gave this order.

The order was placed, although it did not yet understand what it meant, and immediately the sergeant returned to the cabin.

After a while, the sergeant came out with a few fireworks.

"Set off high in the air, one every quarter of an hour, until dawn!"

After a few breaths, a beam of flame rose into the sky, unusually bright in the dark night sky.

"The lantern is lit in a quarter of an hour, just a few breaths, and the time should be short."

When the fireworks also drifted away in the night sky, Yang Congyi left a sentence and turned back to the cabin.

From this moment on, this ship became the pilot ship at the front of the fleet!

The next six or seven ships had to follow this sea ship, and he had to be cautious, and he had to go to the stern to help identify the direction and help with navigation.

The sergeant in the helm cabin was very nervous when he saw Yang Congyi coming in, he had no navigation target, and he didn't know how to adjust the direction.

In the dark, it's not so much how you adjust your direction, it's not about not doing it at will.

Yang Congyi took advantage of the faint light to look at the needle pan, saw that the direction was normal, and kept sailing to the southwest, so he said: "Very good, the tail rudder does not move, continue to sail." ”

After saying that, he sat down next to the sergeant who was operating the tail rudder.

It was a very long night.
